A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body may include a sheet base provided in a direction crossing a vacuum space between a first plate and a second plate, and at least one sheet protrusion that protrudes from the sheet base in at direction toward one of the first plate or the second plate to maintain an interval between the sheet base and the one of the first plate or the second plate.

Vacuum adiabatic body and refrigerator

A vacuum adiabatic body of the present embodiment may include a first plate, a second plate, a seal configured to seal the first plate and the second plate to provide a vacuum space, and a support configured to maintain the vacuum space. Optionally, the support may include a first support having a first support plate formed in a grid shape, and a plurality of spacer coupling portions configured to protrude from the first support plate. Optionally, the support may a second support having a second support plate formed in a grid shape, and a plurality of spacers configured to protrude from the second support plate and coupled to each of the plurality of spacer coupling portions to form a plurality of bars together with the plurality of spacer coupling portions. Optionally, the support may a radiation resistance sheet supported by a portion of the plurality of bars and spaced apart from at least one of the first support plate and the second support plate. Optionally, the plurality of spacer coupling portions may be arranged in a plurality of columns and a plurality of rows in the first support plate. Optionally, only a spacer coupling portion having the same shape may be provided in some columns of a plurality of columns, and spacer coupling portions having a different shape may be provided in some other columns.

An vacuum adiabatic body includes a first plate, a second plate, and a support configured to maintain a vacuum space between the first and second plates. The support includes a support plate supported on an inner surface of one of the first plate and the second plate and a bar extending from the support plate. The bar contacts an inner surface of the other of the first plate and the second plate. The one end of the bar has a cross-section less than that of the other end of the bar.
